ZM120 06.130.001 Shaft (Right Long, from Coupling to Wheel)

ZM120 06.130.001 Shaft (Right Long, from Coupling to Wheel) for ZM-120

The ZM120 06.130.001 shaft is a solid steel drive shaft for the right span of the ZM120 06.100.000-05 differential running axle, designed to transmit torque from the elastic coupling connecting flange directly to the hub of the right drive wheel. It is utilized on self-propelled grain throwers of the ZM-120U series manufactured by Zavod Moroza, as well as during the modernization and retrofitting of running systems on alternative grain thrower series when transitioning to a gearless drive layout featuring an independent gearmotor and pneumatic wheels (smooth ride).

The component is supplied separately (as a bare machined shaft without bearing assemblies, connecting flanges, or fastening elements), serving as a rational solution for targeted repairs of the right running gear span when the shaft itself exhibits mechanical wear beneath the bearings or keyway damage, while associated components remain fit for continued operation.

Technical Specifications of the ZM120 06.130.001 Shaft

• Catalog number - ZM120 06.130.001 (base shaft of the "Complete Shaft Assembly" ZM120 06.130.000)
• Application - right side (span from the elastic coupling to the right drive wheel) of the ZM120 06.100.000-05 running axle for ZM-120U grain throwers
• Purpose - transmitting torque from the drive elastic coupling to the right wheel mounting flange (hub)
• Material - solid round bar stock made from calibrated structural steel featuring machining and milled keyways
• Design parameters - uniform solid diameter of Ø30 mm along the entire length of the shaft (step-free)
• Keyway configuration - the inner end features a longitudinal keyway for an 8x7x45 key, while the outer end features a T-shaped connection (a longitudinal keyway for an 8x7x50 key and a transverse groove for the ZM120 06.100.009 retaining plate)
• Quantity per machine - 1 pc.
• Country of manufacture - Ukraine

Design Features and Operation within the Kinematic Chain

The solid Ø30 mm steel profile ensures high torsional rigidity of the shaft. The shaft is machined from a constant-cross-section steel round bar without technological necking or diameter transitions along its entire length-preserving high component strength when transmitting substantial torque from the gearmotor and preventing elastic shaft deflection during independent movement of the grain thrower or towing across uneven threshing floors.

The keyway configuration is engineered to accommodate the specifics of mating with adjacent assemblies. A classic longitudinal keyway for an 8x7x45 mm key is milled on the inner end of the shaft, securing the ZM120 06.140.000 connecting flange of the 2101-2202120 elastic coupling. The outer (wheel) end features a T-shaped keyway connection-where the longitudinal keyway for an 8x7x50 mm key transmits torque to the ZM120 06.150.000 wheel mounting flange, and the transverse slot accommodates the hardened ZM120 06.100.009 retaining plate, which bolts to the wheel hub to eliminate axial shifting and wheel slippage off the shaft during maneuvering.

External bearing supports ensure smooth rotation across the entire drive line. During running axle assembly, the shaft passes through support bearing assemblies (specifically standard H 026.058 cast-iron housings with H 026.163 covers), which absorb radial loads and maintain precise shaft alignment from the elastic coupling to the wheel.
